Summary: The study examines the adsorption kinetics and thermodynamic properties of a binary mixture on a square lattice using RSAD method. It found competitive adsorption and cooperative phenomena between different components, with species replacement and peak coverage values observed when one component follows RSA model and the other follows RSAD model.

Summary: In this paper, a binary quantum droplet and its effective model are studied. By removing the dynamical instability in the phonon energy, the extended Gross-Pitaevskii equation describing density fluctuations is derived, and the phase diagram of a binary Bose system is obtained.

Summary: Transport properties of mixtures in the warm dense matter (WDM) regime, such as ionic diffusion and viscosity, are crucial in natural astrophysics. In this study, extensive ab initio molecular dynamics (AIMD) simulations were performed on a quasisymmetric binary nitrogen-oxygen (N-O) mixture in a wide range of warm dense conditions (8-120 kK and 4.5-8.0 g/cm(3)). The results showed that the change of proportions in N-O mixtures has only a slight effect on viscosity and diffusion in the strong-coupling region. Additionally, a global pseudo-ion in jellium (PIJ) model was developed and validated for ionic transport calculations, providing a promising alternative approach with relatively low computational costs compared to AIMD simulations.

Summary: This paper proposes a novel vapor-injection Joule-Thomson refrigeration cycle with mixed-refrigerant. The introduction of the compressor with vapor-injection can reduce the pressure ratio of each compression stage, thus reducing the compressor power and discharge temperature. The thermodynamic analysis results show that the performance of the novel cycle is better than that of the basic Joule-Thomson cycle.

Summary: This study examines placing a rigid spherical particle into a binary fluid mixture near the demixing critical point, finding that the particle exhibits motion under an imposed composition gradient, leading to the emergence of a diffusiophoresis mechanism which has not been previously considered.

Summary: In this study, molecular dynamics simulations and experiments were used to investigate a binary mixture of water and an amphiphile. Three distinct solution regimes were identified, with the water percolation threshold closely correlated with minima in excess volume and excess enthalpy. Structural analysis revealed an interplay between local interactions and solution nanostructure, determined by the relative strength of water-water and water-amphiphile hydrogen bonding interactions.

Summary: The Marangoni flow occurring near the liquid-gas interface is crucial in determining the drying process and the final dried deposit pattern during the evaporation of a multicomponent droplet. In this study, particle image velocimetry was used to measure the interfacial Marangoni flows near the apex of a binary mixture droplet, revealing distinct multiple flows over time.

Summary: Two parameters, NII and NIA, are introduced for analyzing the variations of thermodynamic properties of binary mixtures based on experimental data rather than theoretical models. These parameters reveal interesting trends and provide insights into the relevance of solvent characteristics in binary mixtures, offering new interpretations of experimental data.

Summary: A theoretical framework is proposed to quantify the thermodynamic properties of multicomponent hard colloidal mixtures. The phase behavior of mixtures of rods with spheres and rods with plates are predicted using this framework, taking into account the liquid crystal phases of both components. The study demonstrates a rich and complex range of phase behaviors, featuring a large variety of different multiphase coexistence regions. The approach can qualitatively account for certain multiphase equilibria observed in rod/plate mixtures and will be useful in tuning the phase behavior of shape-disperse mixtures in general.

Summary: This study investigates the nucleation process of a binary mixture of patchy particles designed to nucleate into a diamond lattice. By combining Gibbs-ensemble simulations and direct nucleation simulations, the role of the liquid-gas metastable phase diagram on the nucleation process is revealed. The strongest enhancement of crystallization is found to occur at an azeotropic point with the same stoichiometric composition of the crystal.

Summary: The RE-Ni (RE = La, Ce, Nd, Tb and Ho) binary systems were thermodynamically optimized using the CALPHAD method. The liquid phase and terminal solid solution phases were modeled using the substitutional solution model, and excess Gibbs energy was described using the Redlich-Kister polynomials. The binary intermetallic compounds REaNib were treated as stoichiometric phases or using the two-sublattice model. The obtained thermodynamic parameters can reproduce the experimental data well. The phase equilibria and thermodynamic properties of the RE-Ni (RE = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er and Y) binary systems were systematically examined, showing a trend with increasing atomic number of the rare earth metals.

Summary: The study found that even in binary lipid mixtures, DOPS and DPPC can form a three-phase coexistence due to the ionization of DOPS headgroups, making the system quasi-ternary. Through experiments and coarse-grained molecular dynamics simulations, it was determined that the stability of the three-phase coexistence is due to attraction mediated by hydrogen bonding between protonated DOPS molecules and reduction of electrostatic interactions at the domain boundaries.
